2${ CU }{ 2 }$S +
3${{O}
{2}}$ ----------->
2${ CU }{ 2 }$0 +
2${{SO}
{2}}$
In this reaction which substance is getting oxidised and which substance is getting reduced? Name reducing agent and oxidising agent.


#2

${ CU }{ 2 }$S is oxidised, whereas since oxygen is getting attached to Cu, so
${ O }
{ 2 }$ is reduced. Thus,
${ CU }{ 2 }$S behaves as reducing agent, whereas
${ O }
{ 2 }$ as oxidising agent.
